As you will use this unit connected to a network, your attention is called to the following security
risks.
ALeakage or theft of information through this unit
BUse of this unit for illegal operations by persons with malicious intent
CInterference with or stoppage of this unit by persons with malicious intent
It is your responsibility to take precautions such as those described below to protect yourself
against the above network security risks.
• Use this unit in a network secured by a firewall, etc.
• If this unit is connected to a network that includes PCs, make sure that the system is not
infected by computer viruses or other malicious entities (using a regularly updated anti-virus
program, anti-spyware program, etc.).
• To prevent unauthorized access, use user-authentication, set user names and passwords, and
limit which users can log in.
• Apply measures such as user authentication to protect your network against leakage or theft of
information, including image data, authentication information (user names and passwords),
alarm mail information, FTP server information and DDNS server information.
• After the unit is accessed by the administrator, make sure to close the browser.
• Change the administrator password periodically. Additionally, save user authentication
information (user names and passwords) in such a way that it is kept out of the hands of third
parties.
• Do not install the camera in locations where the camera or the cables can be destroyed or
damaged by persons with malicious intent.
Network security

6
When the product is accessible from the
Internet
To prevent unauthorized access, note the following.
• Leave user authentication turned on.
• Periodically change passwords that are used
to access the product.
Refer to the Operating Instructions for
information about how to change passwords.
To keep on using with stable performance
Do not use this product in hot and humid
conditions for a long time. Failure to observe this
causes component degradation resulting in life
shortening of this product. Do not expose this
product to direct heat sources such as a heater.
Usage such as switching the power ON/OFF
frequently could lead to failure of the camera.
Handle this product with care.
Do not drop this product, nor apply shock or
vibration to the product. Failure to observe this
may cause trouble.
Do not subject dome cover to strong impact.
Doing so may cause damage or immersion.
Do not directly touch the dome cover and
lens.
A dirty lens or dome cover causes deterioration of
picture quality.
When an error is detected, this product will
restart automatically.
This product will be inoperable for around
2minutes after the restart just as when the power
is turned on.
About the automatic status detection
function
When this product malfunctions due to exogenous
noise, etc. for 30 seconds or more, the product
will automatically restart and will return to normal
state. When the product is restart, initialization will
be carried out as when the power of the product
is turned on. When the product repeatedly resets,
exogenous noise level around the product may
be high and that may cause malfunction. Contact
your dealer for instructions.
Periodically images on the screen appear to
be distorted
When the camera is installed in a location where
it is subject to small vibrations (for example, when
it is installed near devices that vibrate), images
may appear distorted and stretched lengthways.
This phenomenon is a characteristic of image
pickup devices that use CMOS sensors and is
caused by the relationship between the periodic
movements of the camera and the timing that the
image sensor reads images. This is not a problem
with the camera. To reduce the possibility of this
phenomenon occurring, install the camera in a
secure location.
About the dehumidifying device
• This product has dehumidifying device
to keep the inside at low moisture level,
preventing condensation and quickly
dissipating dew if produced.
• Dew may be produced depending on the
conditions of temperature, humidity, winds,
and rain, and it may take time to dehumidify.
• The dehumidifying device is mounted inside
the enclosure. In order to maintain normal
operation of the dehumidifier function, do
not caulk (fill the clearance with sealants or
other materials) the clearance between the
enclosure and the ceiling or wall.
Dehumidifying
device
What to do if “WARMING UP-PLEASE WAIT”
appears on the display.
This message indicates that the temperature
inside the camera has become extremely low.
The camera will be automatically restarted when
the inside the camera is warmed up by the built-in
heater. Please wait for a while.
Precautions for use

7
We shall not be liable for content
compensation, losses of recorded or
edited content and any direct or indirect
consequent damages caused by failure to
record or edit due to faults with this unit or
the SD memory card. In addition, the same
provisions apply after unit is reparied.
About the CMOS image sensor
• When continuously shooting a bright
light source such as a spotlight, the color
filter of the CMOS image sensor may
become deteriorated and this may cause
discoloration. Even when changing the
fixed shooting direction after continuously
shooting a spotlight for a certain period, the
discoloration may remain.
• When shooting fast-moving subjects or
objects crossing the shooting area may look
to be bending askew.
Cleaning this product body
Be sure to turn off the power before cleaning.
Failure to observe this may cause injury.
Do not use benzine, thinner, alcohol, or any other
types of solvents or detergents. Otherwise, it may
cause discoloration. When using a chemical cloth
for cleaning, read the caution provided with the
chemical cloth product.
• Do not loozen or remove screws unless
instructed to do so in the product
documentation.
Cleaning the lens
Use a lens cleaning paper (used to clean camera
lenses or lenses of spectacles). When using
solvent, use an alcohols solvent and do not use a
glass cleaner or a thinner.
Cleaning of the dome cover
• When cleaning the dome cover, hose or spray
fresh water that is not containing lubricant
agent or silicon substances and wash away
adherents such as grain of sand. If dirt is hard
to remove, use a sponge soaked into the
fresh water mentioned above and wipe off.
• Do not wipe the cover with a dry cloth.
(Using dry cloth may spread oil constituent
adhered to the surface, and it may result in
damaging the rain wash coating.)
• If dirt cannot be wiped off with a damp cloth,
use a neutral detergent and sufficiently rinse
off the detergent.
• Do not use organic solvent such as benzine
and thinner.
• Before using a spray, abandon a few sprays
to eliminate impurities.
• The mark of light-shielding parts left inside
the dome or dirt on the dorm cover may
influence the reflection of infrared rays.
Therefore, remove those marks and dirt using
cleaning paper.
• Improper cleaning of the dome cover may
cause the rain wash coating to become
less effective. In this case, in order to have
effective rain wash coating, a new dome
cover must be purchased to replace the
existing dome cover. Consult with your dealer
or construction contractor.
About the rain wash coating
Due to effectiveness of the rain wash coating,
drops are likely to be accumulated right under the
camera and it may cause a partial distortion of the
video.
